One of the more troubling parts of the survey is students'
responses to questions about sexual assault. The vast majority of
sexual assaults at Harvard — more than 80% — went unreported,
according to The Crimson's survey.

Twelve percent of women in the Class of 2014 responded that they
were sexually assaulted at Harvard, but only 16% of victims
reported their assault. Two percent of men said they were
sexually assaulted at Harvard.

However, as The Crimson notes, these figures may be better than
other college campuses:

By way of comparison, a 2007 study found that 19 percent of
college women at large four-year universities experienced an
attempted or completed sexual assault during their undergraduate
careers. Some researchers estimate that 95 percent of sexual
assaults on college campuses may go unreported.
